A Review Synthesis and Biological Evaluation of Plant-Based Metallic Gold Nanoparticles

Nanotechnology has become a trending area in the field of science and technology. It has made great advances with the development of functional, engineered nanoparticles. The better advancements made towards the synthesis of nanoparticles using plant materials have become a major focus of researchers because of their advantages including high stability and loading capacity. Recently, zinc oxide nanoparticles have drawn the attention of several researchers owing to their several biological applications including anticancer and antimicrobial activities. Different techniques have been employed for the production of gold nanoparticles due to their elaborated applications in different interdisciplinary fields. The synthetic procedure of plant-based nanoparticles has attracted a keen interest of various researchers as the synthesis is comparatively fast, safe and light and can be followed under basic room conditions without the requirement of any advanced synthesis requirements. Every part of the plants can be used for the synthesis of nanoparticles. Gold nanoparticles play a pivotal role as the most active, environment friendly and biocompatible towards a greener approach. In this review paper, we report highlighted about the various plants extract, which have been used for the synthesis of gold nanoparticles and their biological evaluation based on previous year’s research and scientific papers and journal and articles.
